Reporting peaked in 2021 at $4,353 and has fallen 96.6% since, to $149 in 2025. Among physician assistant clinicians in DE with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.

How this compares
$5,181 in reported general payments places this provider in the 95th percentile of 527 physician assistant providers in Delaware.
Medicare billing
What this is not: this is the amount Original Medicare Part B allowed for services this provider billed in 2024. It is not their income. It excludes Medicare Advantage — now more than half of all Medicare enrollment — along with Medicaid and all commercial insurance, and it is gross practice revenue before staff, rent, supplies and malpractice premiums. CMS also suppresses any figure covering ten or fewer patients, so low-volume providers appear smaller than they are.
